Maybe you’ve just seen the latest X-Men film. A lot of people have, so odds are pretty good. And if it left you wanting to know more about the original Days of Future Past storyline, but tracking down the trade paperback and then, like, reading it sounds like a lot of work, here’s a game you’ll want to check out.

Uncanny X-Men: Days of Future Past is out now for your favorite iOS device, and it aims to faithfully re-create the source material the way it originally appeared. This means that it’s the assassination of Senator Kelley that brings forth the robopocalypse (that character died in the first film, so he wasn’t available to die in the new one), and it’s Kitty Pryde, not Wolverine, who goes back in time to set things right.

Sure, you can play the whole game as Wolverine if you want, but if you’re a purist, you have a chance to do it “right.”
